With the release of the iPhone on T-Mobile, now every U.S. carrier has access to the device. This means that everyone has a choice of carriers, and T-Mobile is pushing hard to make it so that you pick them. Now the iPhone — the 4, 4S and 5 — is available on our favorite pink carrier, and we want to know if you’ve switched over yourself.

Here in the U.S., T-Mobile has been the last carrier without the iPhone — at least officially. Unofficially, people have been buying iPhones and jailbreaking them to use on T-Mobile for years, because the AT&T model could be used with a T-Mobile SIM card.

But now, T-Mobile is carrying the iPhone, and they’re doing it without a contract. That’s right, you pay $99 for the iPhone initially, then $20/month for two years for a total of $580. The overall numbers aren’t quite a slam dunk, but it’s still pretty nice for people who want to get away from contracts.

If you live in the U.S., would you switch to T-Mobile for the iPhone? Let us know in the poll to the right!
